Answer:
/*C++ program to read and print students information using two classes and simple inheritance.*/
#include <iostream>
using namespace std;
//Base class
class std_basic_info
{
private:
char name[30];
int age;
char gender;
public:
void getBasicInfo(void);
void putBasicInfo(void);
};
//function definitions
void std_basic_info::getBasicInfo(void)
{
cout << "Enter student's basic information:" << endl;
cout << "Name?: "; cin >> name;
cout << "Age?: "; cin >> age;
cout << "Gender?: ";cin >> gender;
}
void std_basic_info::putBasicInfo(void)
{
cout << "Name: " << name << ",Age: " << age << ",Gender: " << gender << endl;
}
//Derived class
class std_result_info:public std_basic_info
{
private:
int totalM;
float perc;
char grade;
public:
void getResultInfo(void);
void putResultInfo(void);
};
//function definitions
void std_result_info::getResultInfo(void)
{
cout << "Enter student's result information:" << endl;
cout << "Total Marks?: "; cin >> totalM;
perc= (float)((totalM*100)/500);
cout << "Grade?: ";cin >> grade;
}
void std_result_info::putResultInfo(void)
{
cout << "Total Marks: " << totalM << ",Percentage: " << perc << ",Grade: " << grade << endl;
}
int main()
{
//create object of derived class
std_result_info std;
//read student basic and result information
std.getBasicInfo();
std.getResultInfo();
//print student basic and result information
std.putBasicInfo();
std.putResultInfo();
return 0;
